  7. Types of Data Quantitative Qualitative

  8. Types of Data/Levels of Data Ratio Quantitative Interval Qualitative Ordinal Nominal

  9. Classify the data obtained with the following questions. _____ Q1. How many pairs of tennis shoes do you own? _____ Q2. How high is your vertical leap measured in inches? [1] less than 12 inches [2] at least 12 inches but less than 24 inches [3] at least 24 inches but less than 36 inches [4] at least 36 inches but less than 48 inches [5] at least 48 inches _____ Q3. What is your favorite physical education activity? [1] baseball [2] basketball [3] football [4] soccer [5] softball [6] tennis [7] volleyball [8] OTHER _____ Q4. What is the best temperature (in F) in which to play football?

  10. Which questions yield qualitative (categorical) data? Which questions yield quantitative (numerical) data? Which questions yield nominal level data? Which questions yield ordinal level data? Which questions yield at least interval level data? Which questions yield data that is discrete? Which questions yield data that is continuous?

  11. Classify the data obtained with the following questions. _____ Q1. How many pairs of tennis shoes do you own? Types of Data Quantitative (Numerical) Qualitative (Categorical) Levels of Data Measurement highest Ratio Interval -------- Ordinal lowest Nominal

  12. Classify the data obtained with the following questions. _____ Q1. How many pairs of tennis shoes do you own? Types of Data Quantitative (Numerical) Discrete Continuous Qualitative (Categorical)  Levels of Data Measurement  highest Ratio Interval -------- Ordinal lowest Nominal At least interval

  13. _____ Q2. How high is your vertical leap measured in inches? [1] less than 12 inches [2] at least 12 inches but less than 24 inches [3] at least 24 inches but less than 36 inches [4] at least 36 inches but less than 48 inches [5] at least 48 inches _____ Q2. How high is your vertical leap measured in inches? [1] less than 12 inches [2] at least 12 inches but less than 24 inches [3] at least 24 inches but less than 36 inches [4] at least 36 inches but less than 48 inches [5] at least 48 inches _____ Q2. How high is your vertical leap measured in inches? Without the categories, it is numerical. With the categories, it is qualitative.
